Emulation-unpack-tools

Collection of scripts to automatically unpack your romsets to the correct format

Short explanation of the usage:

dc_unpack.sh

Originally created to unpack my Dreamcast rom collection but later expanded to use for other (cd-based) systems as well. You will need to have the following dependencies:

• unecm (instructions see below)
• unrar
• 7z
• unzip

Please consult your distrubution on how to install this.
The syntax is as follows:

./dcunpack.sh <MODE> <SOURCE dir> <DESTINATION dir> <OPTION m>

• <MODE>:
  
  f = all your roms are in archives directly in the SOURCE DIR e.g.
  

<SOURCE DIR>
|_<SONIC ADVENTURE 1.RAR>
|_<VIRTUA FIGHTER 3.RAR>

d = all your roms are in separate dirs in your SOURCE DIR e.g.

<SOURCE DIR>
|_<SONIC ADVENTURE 1/>
|  |_<SONIC ADVENTURE 1.RAR>
|_<VIRTUA FIGHTER 3>
   |_<VIRTUA FIGHTER 3.RAR>

• <SOURCE dir>: The directory containing your roms
• <DESTINATION dir>: The (new) directory to where you want to extract your roms
• <OPTION m>: (makedir) creates separate directories to extract each archive to. Only use when the archives don't containt any folder and only in file mode

This script will do the following steps:

• Find archive files (.rar, .zip...) and extract them to the <DESTINATION dir>
• Check if there are .ecm files present and extract them
• Clean up partially (rar) archives & .ecm files
• Display a list of extracted games & save them under <DESTINATION dir>/extracted.txt

nrgbatch.sh

Used to convert .nrg files to .iso Usage:

usage: ./nrgbatch.sh <DIR>

With <DIR> the directory where your .nrg files are located. After all files are converted you also have the possibility to delete the .nrg files (WIP - not implemented yet)

unecm installation instructions for Debian/Ubuntu

1. Download source from https://raw.githubusercontent.com/MaddTheSane/ECMGUI/master/unecm/unecm.c
2. compile using the folowing command gcc -o unecm unecm.c
3. Copy the unecm file to /usr/bin so you can call the program system-wide (cp unecm /usr/bin)
   
   All written & tested on on debian 10 - possibly also works under other distros Please test this first on a copy of soms roms if the given mode & option is correct
   I have not tested every possible scenario so code could be improved
